3. Setup Instructions
Follow these steps to set up your ieGeek WiFi OBD2 Scanner and connect it to your smartphone:
- Download the Application: Search for and download a compatible OBD-II diagnostic application (e.g., EOBD-Facile, Torque, Car Scanner) from the Apple App Store (for iOS) or Google Play Store (for Android).
- Connect the Device: Locate your vehicle's OBD-II diagnostic port, typically found under the dashboard on the driver's side. Plug the ieGeek WiFi OBD2 Scanner firmly into this port.
- Start the Engine: Turn on your vehicle's ignition or start the engine. The scanner will power on automatically.
- Connect via WiFi: On your smartphone, go to your WiFi settings. Find and connect to the WiFi network broadcast by the ieGeek scanner. The SSID is typically 'WiFi'. The default IP is 192.168.0.10 and Port is 35000.
- Launch the Application: Open the diagnostic application you downloaded. Within the app, you may need to configure the diagnostic tool settings and select your vehicle's model to establish a connection.
Important Note: To improve the product's lifespan, do not leave the scanner permanently plugged into the diagnostic port when not in use. Only connect it during diagnostic sessions.

4. Operating Instructions
Once the ieGeek WiFi OBD2 Scanner is connected to your vehicle and smartphone, you can perform various diagnostic functions through your chosen application:
- Read Error Codes: Access the 'Read Codes' or 'Diagnostic' section in your app to retrieve Diagnostic Trouble Codes (DTCs) stored in your vehicle's Engine Control Unit (ECU). These codes indicate specific issues detected by the vehicle's system.
- View Real-time Data: Monitor live sensor data such as engine RPM, vehicle speed, fuel system status, oxygen sensor readings, coolant temperature, and more. This data can help in diagnosing intermittent problems or verifying repairs.
- Clear Fault Codes: After addressing a vehicle issue, use the 'Clear Codes' or 'Erase Faults' function in the app to turn off the Check Engine Light (MIL - Malfunction Indicator Lamp) and clear stored DTCs from the ECU.
- Freeze Frame Data: Some applications allow you to view 'Freeze Frame' data, which captures a snapshot of sensor readings at the exact moment a fault code was set.
- I/M Readiness Status: Check the status of various emission-related monitors to determine if your vehicle is ready for an emissions test.
The specific interface and terminology may vary depending on the diagnostic application you are using. Refer to your chosen app's documentation for detailed usage instructions.

5. Maintenance
The ieGeek WiFi OBD2 Scanner requires minimal maintenance. To ensure optimal performance and longevity:
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Cleaning: Wipe the device with a soft, dry cloth if it becomes dirty. Do not use harsh chemicals or abrasive cleaners.
- Connection: Avoid leaving the device permanently plugged into your vehicle's diagnostic port. Disconnect it after each use to prevent unnecessary power draw and prolong its lifespan.
6. Troubleshooting
If you encounter issues while using your ieGeek WiFi OBD2 Scanner, consider the following:
- No Connection to Device WiFi:
- Ensure the scanner is firmly plugged into the OBD-II port and the vehicle's ignition is on.
- Verify that your smartphone's WiFi is enabled and you are selecting the correct network (SSID: 'WiFi').
- Try restarting your smartphone and the vehicle.
- App Not Connecting to Scanner:
- Confirm that your smartphone is successfully connected to the scanner's WiFi network.
- Check the app's settings to ensure it is configured to connect via WiFi and the correct IP (192.168.0.10) and Port (35000) are entered if required.
- Ensure the app is compatible with your operating system and the ieGeek scanner. Some apps may have specific requirements.
- Try using a different compatible diagnostic application.
- No Codes or Incorrect Readings:
- Verify your vehicle's compatibility with the OBD-II standard and the scanner (12V gasoline/diesel, post-1996 models).
- Ensure the vehicle's engine is running or the ignition is in the 'ON' position.
- Some advanced features or code clearing might require a paid version of the diagnostic application.
- Device Overheating: Disconnect the device immediately. Ensure it is not left plugged in for extended periods when not actively performing diagnostics.
